Daniel, Right! There's nothing more "unprofessional" to an adult in school than arriving to a class with the teacher unprepared. It's strange that some students themselves may not be prepared, but even if they don't say anything, in their mind, they recognize the failure of their teacher to be ready to conduct class. Also, we deny our students access to us during this valuable time period - immediarely before class begins. This time can be used to answer questions, ask questions, or just chat. And needless to say, we're paid to be ready. Barry Westling
